In theoretical network science, the Turing switch is a logical construction modeling the operation of the network switch, just as in theoretical computer science a Turing machine models the operation of a computer. Both are named in honor of the English logician Alan Turing, although the research in Turing switches is not based on Turing's research. Some introductory research on the Turing switch was started at the University of Cambridge by Jon Crowcroft (Homepage).

  • إن مُبدل تورنغ عبارة عن بنية منطقية مشابهة لـ آلة تورنغ. ويُحدد مُبدل تورنغ هيئة عمل جهاز توزيع الشبكة الأساسي في شبكة مفاتيح التبديل، مثله في ذلك مثل آلة التورنغ التي تحدد هيئة عمل الكيان الحاسوبي الأساسي. ولقد تمت تسمية كل من مُبدل تورنغ وآلة تورنغ نسبة إلى عالم المنطق الإنجليزي آلان تورنغ. وكانت بعض الأبحاث التمهيدية قد بدأت في جامعة كامبريدج وقام بها جون كراوكروفت. في حقيقة الأمر، كان كراوكروفت يقترح أنه بدلاً من استخدام أجهزة حاسوب للأغراض العامة في تحويل الطرود، ينبغي خفض العمليات اللازمة لمنطق تطبيق معين، ثم يُنفذ منطق التطبيق المعين هذا باستخدام مكونات بصرية. لكن هذه الأبحاث لم تعتمد في الواقع على أبحاث تورنغ. يتكون مُبدل تورنغ من نسيج تبديل، وواجهة واحدة أو أكثر للإدخال (يشار إليها أيضًا بالمصادر) وواجهة أو أكثر للإخراج (أحواض) وإجراء تقريري لتحديد واجهة الإدخال الخاصة بواجهة الإخراج. وفي بعض الأحيان يشار للواجهات بالمنافذ. يصل الطرد (الخلية أو الوحدة المُحولة) إلى واجهة الإدخال، فيقوم الإجراء التقريري بتحديد واجهة الإخراج المناسبة، فيتم نقل الطرد عبر نسيج التبديل إلى واجهة الإخراج. والطرد عبارة عن رمز أو سلسلة من 1 و0. وتتصل واجهة الإدخال بخط الإدخال، وواجهة الإخراج بخط الإخراج. ويُقال إن خط الإدخال يغذي واجهة الإدخال؛ وواجهة الإخراج تغذي خط الإخراج.

  • In theoretical network science, the Turing switch is a logical construction modeling the operation of the network switch, just as in theoretical computer science a Turing machine models the operation of a computer. Both are named in honor of the English logician Alan Turing, although the research in Turing switches is not based on Turing's research. Some introductory research on the Turing switch was started at the University of Cambridge by Jon Crowcroft (Homepage). In essence, Crowcroft suggests that instead of using general-purpose computers to do packet switching, the required operations should be reduced to application specific logic and then that application specific logic should be implemented using optical components. The work is not actually based on Turing's research. A Turing switch consists of a switched fabric, one or more ingress interfaces (also referred to as sources), one or more egress interfaces (sinks), and a decision procedure to determine an egress interface given an ingress interface. Interfaces are sometimes referred to as ports. A packet (cell or switched unit) arrives at an ingress interface, the appropriate egress interface is determined by the decision procedure, and the packet is then transported across the switching fabric to the egress interface. A packet is a symbol or sequence of 1's and 0's. An ingress interface is connected to an ingress line and an egress interface to an egress line. The ingress line is said to feed the ingress interface; the egress interface feeds the egress line. (en)

Em essência, Crowcroft sugere que no lugar de usar computadores de propósito geral para fazer trocas de pacotes, a operação requerida deveria ser reduzida para lógicas específicas de aplicação e então implementadas utilizando componentes ópticos. Esse trabalho não está de fato baseado na pesquisa de Turing. Um Turing switch consiste de uma , uma ou mais interfaces de entrada (também referido como "source"), uma ou mais interfaces de saída, e um procedimento de decisão para determinar uma interface de saída dada a interface de entrada. Interfaces são algumas vezes também chamadas de portas. Um pacote chega por uma interface de entrada, a interface de saída apropriada é determinada pelo procedimento de decisão, e o pacote é, então, transportado através da fábrica de switches até a interface de saída. O pacote é um símbolo de sequência de 1's e 0's. Uma interface de entrada está conectada a uma via de entrada, uma interface de saída a uma via de saída. Uma via de entrada é usada para alimentar a interface de entrada; a interface de saída alimenta a via de saída. (pt)
